Linear regression is a linear approach to modeling the relationship between a scalar response (or dependent variable) and one or more explanatory variables (or independent variables).

the term "regression" is coined by Francis Galton.

it seems Galton did't use the term "Linear regression" in his paper, so, who and when coined the term "Linear regression"?
